Apple Shares Charging Details for New Dual USB-C Power Adapters

Following yesterday's launch of orders for the two new 35-watt dual USB-C power adapters introduced at WWDC, Apple has posted a new support document outlining how power is split when devices are connected to both ports.

Under most scenarios, the 35 total watts will be split evenly between the two connected devices, with the exception being when one of the devices has relatively low power requirements, such as an Apple Watch or AirPods case.

  • If you connect a Mac notebook and an iPhone or iPad, each device receives up to 17.5W.
  • If you connect an ‌iPhone‌ and an ‌iPad‌, each device receives up to 17.5W.
  • If you connect a Mac notebook or ‌iPhone‌ and an Apple Watch or AirPods, the Mac notebook or ‌iPhone‌ receives up to 27.5W and the Apple Watch or AirPods receive up to 7.5W.

The standard version of the dual USB-C adapter is available worldwide and has a removable plug head for compatibility with international plug heads and extension cables. The compact version is only available in the U.S., Canada, China, Japan, Mexico, and a few other countries that use the Type A plug style. Both versions are priced at $59 in the United States, and the new adapters will ship with higher configurations of the new MacBook Air launching next month.

Does it run iOS as well, like the Studio Display?

They couldn’t male it 40W, so each device would receive 20W? Or 10/30 for watch and Mac/iPhone since 13 pro max can receive up to 27W.

I'm baffled they didn't do higher wattage. I know MBA is not exactly high-powered, but why not do a dual charger that could fast charge both an iPhone and the mac?

Also, and I almost can't believe I'm asking for this, but why do I have to get a charger bundled? I have 2 x 100w with triple USB-C and 1 USB-A. I don't need new chargers for the foreseeable future.

Maybe the charger will help with running Stage Manager on non M1 iPads ?

Next iPhone that is iPhone 14 will require exact 19.8524524858 W to charge at full speed otherwise it will default to slow 5W charging. Apple will also release a 39.7049049716 W dual adapter rendering current 35W adapter obsolete.

So all the suckers would have to re-buy the new 39.7049049716 W so that their shiny new iPhone 14 and 14 Pros continue to charge at optimum speed and also optimally reduce their battery health as per Apple's recommendations. New replacement batteries will also be in stock on day 1 along with super huge DIY kits.

This cycle will repeat at the release time of iPhone 15.
